Abstract: According to an embodiment, an implantable hearing aid system is disclosed. The implantable hearing aid system includes an external unit which includes an electronic unit operationally coupled to a first inductive coil arrangement configured to transmit power and/or data signals, and where the first inductive coil arrangement includes a loop structure with coils wound around and along at least a part of length of the loop structure, and the loop structure comprises an opening. Furthermore, the implantable hearing aid system includes an implantable unit which comprises a second inductive coil arrangement configured to form a transcutaneous link with the loop structure and to receive the power and/or data signals over the transcutaneous link, and where the second inductive coil arrangement is configured to be implanted fully or partially within a part of an ear of a user of the implantable hearing aid system. The external unit includes a housing and an earhook, and where a first end-face of the loop structure is arranged within the earhook and a second end-face of the loop structure is arranged within the housing or within the earhook.
